Griswold Owner

Tim Griswold

I began my career in garage doors at 14, working for my father’s business during summer breaks. When his business was acquired by a larger company with the contract for all overhead doors and security gates at Denver International Airport (DIA), I transitioned to a full-time role at DIA at 19. Over the next three years, I gained extensive experience in door and gate installation, earning certifications in welding and equipment operation. After a decade with the company, I joined a larger firm, taking on more significant projects and eventually becoming a site foreman. Six years later, I advanced to the role of general manager at another overhead door company, where I honed my skills in sales, bidding, and project management. With over 20 years of industry experience, I decided to partner with my father to start our own business. Our goal is to provide exceptional service and outstanding customer care, setting us apart from other companies.
